Hi, I run openvswitch on Ubuntu and KVM. The vnet that i talk is the 'tap' on other distrib. The network interface for the VM. Each VM has one or more network interface, we see there on hypervisor under the name : vnet (tap). Number for vnet is random (i guess .. ) and when i shutdown my VMs and reboot it, number's vnet (tap) is modified : first VM start has vnet0, the 2nd vnet1. if i shutdown and restart the 2nd before the first then the 2nd has vnet0 and the first vnet1. If i look the cacti's graph then i must go on the hypervisor and see which VM attach to which Vnet at precise time
